' Specification of Letters Patent.

. Patented June 9, 190a.

Application filed August 21, 1907. Serial No. 389,423.

To all whom it may concern:

Be it=known that I, BERNARD A. KENNE- .POHL, a citizen ofthe United States, residing in Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements Water-Heaters,

of whichthe following is .a full and accurate specification and exposition, being such as with absolute exactitude.

The object of my invention, broadly speakr will-enable others to make and use the same ing, isto provide a water-heater which will be strong and durable in construction; being so formed as'to occupy a minimum. amount of space; which will be; inexpensive to install and maintain; by which water may-be easily I I and quickly heated to'the temperature'da which are new and useful will be in the appended claim.

One manner for carrying outthe principles of my invention, and that, which in practice accentuated hasbee-n found to be the most desirable, is

shown most clearly in the accompanying the, upper end of the drawings, inwhichg Figure 1 is a side elevation of my invention complete and in operative position, portions bein shown as broken away in order to more clear y show the interior construction of the invention.v Fig. 2 is a plan view of the upper end of the heater. Fi 3' is a lan view of eater wlth the heat domeremoved. Fig. 4 is a central cross sectional view of-the heater. And Fig. 5 is a plan view of the lower end of the heater.

Similar indice's denote like partathrou'ghout the several views of the drawings.

In order that" the construction and operation of m invehtion may bemore clearly understoo tion thereof whichIwill describe the several parts as briefly and-"as compactly a's'I may.

In this instance the letter A designates the body of the heater, which in fact is 'a'cylin- -is permanently secured, as by tap -and-"ris es above the top B forming a heat turned articular advantages of :my lnventionwilL e brought out in the course of the specification, and the features and its advantages "be fully appreciated I will now take up a detail exposi drical oblong casing adapted to stand in a vertical position as shown. The upper end of the body is closed by the topB, .an'dthe lower end is closed by theconcavo-conveX bottom C. The bottom is formed to curve.

upwards within thebody to form a com aratively lar'gecombustion chamber D, as s own in Fig. 1, A I a v The numerals 1, 2 and 3 denote flues which connect. the top H and the bottomC and open therethroughf I The letter E denotes the heat dome, which bolts, to

chamber into which opens the upper end of the flu'e's. In the top of said dome is an aperture ada tedto be opened or closed by t e dam er which damper is adapted to be eing mounted on the pivot G. A second aperture is formedthrough the heatdome in which aperture is threaded the esve I from which a pipe J may be extended to any point desired, asto the outside of the building. 7

The heater is carried by a pedestal K, to

the upwardly extending arms of which it is secured, and by which the heater is supported at the desired distance from the floor'as The numeral 4 denotes the outlet pipe extending through the top B and by means of which water may be withdrawn from the incape pipe II. Said pipe H is provided with a terior of'the heater and controlled by' the faucet 5, which latter may be located at any convenient point desire Thenumeral 6 denotes an inlet pi e, controlled by the valve 7, throu h WlliG water may be injectedinto the boi er.

The numeral 8 denotes a gas'burner lo cated centrally in the combustion chamber D, bein 'connected-to themixenQ, with a pipe 10 l eading out therefrom. to the fuel supply, and controlled by the valve 11.

The numeral 12 designates a faucet through which water may be withdrawn from the heater, andby which the heater may be drained. i

O eration: From the above the reader will ave opined that the heater is to be supplied with water; gas is then allowed to flow through the pipe '10, then lighted, and radiate lie 1, 2 and 3, and if thefdamper F be 0 en then the surplus heat will pass out into t e room through the aperture which the damper controls, or if preferred said a erture may be closed by the damper and t e'valve I may be opened, thereby allowing the surplus heat from the burning gas to be conducted out- I side the building in which the heater is located. The particular feature of this'in vention, however, is that I' provide a compara- 'tiv'ely large heating surface, com rising the combustion chamber below, the eat-domeabove, and a plurality of fines passing through the heater longitudinally and connecting said combustion-chamber and heat-dome. In operation, after the heater has warmed up, and the flame from the burner is in good trim,

then the escape of the heat from the dome may be retarded or entirely shut ofi, particularly if the blaze be turned low, thereby utilizing practically all of the heat from the fuel.

From the foregoing, it will be understood that under certain conditions both the damper F and valve I may be open. Such would be the arrangement, for instance, in

order to secure the maximum -ar'nount of draft tirough the flues, with a resultant correspbn ingly rapid heating of the water. When, hdwever, it would be desired to reduce the eipenditure of heat, or'to varvthe discharge of the products of combustion, either or both 0 said valves would be either "wholly or partia ly closed, as desired. After the water is once heated, and unless a large quantity of cold water is admitted to the boiler on account of the use of the heated water, the amount of gas or fuel required to maintain the water in .the boiler at. a proper temperature would be as a matter of course reduced, and when less heatis employed it may bere'q'uired or desirable to modify the position of thevalves accordingly,

Ireserve the privilege of making changes in the details of construction without departing from thes irit of my invention or sacrificing any of t e advantages thereof.

Having now fully shown and described my I invention and the best means-for its construction and 0 eration to me known at this time, what I c aim and desire to secure by Letters Patent .of the United States, is

A water heater comprising an elongated water-tank which is round in cross section having means whereby :water maybe" injected thereinto and means whereby the water maybe withdrawn therefrom, a concavo-convex permanent bottom for the tank located above the lower end thereof forming l a combustion chamber,;a permanent top for the tank, a heat-dome secured on the top, a plurality of permanent plain heat-fines extending longitudinally through the tank and connecting the top and the bottom and con-' neoting the interior of the combustion cham- BERNARD A.
